CLARINET.

SPECIFICATION forming part of Letters Patent No. 623,422, dated April 18, 1899.

Application filed October 22, 1898. Serial No. 694,263. (No model.)

To aZZ whom, it may concern.

Be it known that we, GUSTAV L. PENZEL and EDWARD MULLER, of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Clarinet, of which the following is a full, clear, and exact description.

' The object of the invention is to provide a new and improved clarinet permitting an easy fingering of the key G-sharp from the keys B-natural and G-sharp without deviating from the usual fingering or compelling the performer to move the little finger of the left hand from the said keys B-natural and O-sharp, the arrangement also permitting an easy trillin g of the key G-sharp.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Referenceis to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of part of a clarinetprovided with the improvement. Fig. 2 is a side elevation of part of the same, and

Fig. 3 is an inverted sectional plan view of the same on the line 3 8 in Fig. 1.

The improved clarinet is provided with the usual tubular bodyA, having a key B-natural 1 and a key O-sharp 2, the finger-pieces 3 and at of which extend over an arm 5, forming an integral part of the finger-piece 6 for the key G-sharp, as is plainly indicated in the draw ings. The linger-piece G is fulcrumed on a pivot 8, carried by the body'A, and on said pivot is also pivoted the key proper, 7, and said finger-piece is normally held in an outermost position by a spring 9, a similar but weaker spring 10 pressing on the key '7, with a tendency to hold the latter open. The finger-piece G is formed beyond its fulcrum with an arm 11, engaging a lug on said key 7, so that when the said finger-piece 6 is pressed the arm 11 is raised, and thereby permits the spring 10 to force the key 7 to swing outward off its seat, and when the finger-piece 6 is released then the spring 9 returns said fingerpiece (5 to an outermost position and also the key 7 to a closed position, owing to the arm and when either finger-piece 3 0rd is released the finger-piece 6 returns to its pormal position and closes the key 7, as above described. In other words, my improvement consists of a key (linger-piece) C-sharp or G-sharp connecting with the E or B and F-sharp or C- sharp keys in order that in performing the said passage it is only necessary to hold down the B or C- sharp keys and raise the right hand instead of gliding from B or C-sharp keys to G-sharp or (J-sharp keys.

Above the free end of the key 7 extends one end of a trillingdever 12, fulcrumed at 13 on the body A, (see Fig. 2,) and the lower end of said lever is engaged at its under side by an arm 1st, carried by the F-sharp ring 15, said lever 12 being normally held with its up per end above the key 7 by a spring 16. (Shown in Fig. 1.)

When it is desired to trill the key G-sharp 7, the operator on pressing the finger-piece G and trilling the ring 15 causes the arm 14.- to actuate the trilling-lever 12, so that the upper end thereof trills the key 7 as the latter stands in an open position, owing to the pressure of the finger-piece 6 above mentioned.

It is evident that by the arrangement described a performer is enabled to readily play the key G-sharp upon pressing either the key B-natural or C-sharp without displacing the little finger of the left hand from the fingerpieces 3 and 4:. Furthermore, the performer is enabled to readily trill the key of G-sharp from the key F-sharp without displacement of the fingers of the right hand to produce the passage- Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. In a clarinet, the combination of a G- sharp key consisting of a pi voted finger-piece formed with a rearward extension and a key proper having a connection with said fingerpieee whereby it will open when the fingerpiece is depressed, but being freely movable independent of the finger-piece when the latter is depressed, a trilling-lever actuated from the key F-sharp and arranged to engage with the key G-sharp proper whereby to trill the same when the finger-piece is depressed, and keys B-natural and C-sharp provided with finger-pieces lying over the rearward extension of the finger-piece of the key Gsha-rp whereby the key G-sharp may be trilled when either of the said B-natural or C-sharp ringerpieces is depressed, as and for the purpose set forth.

2. A clarinet provided with a G-sharp key consisting of a finger-piece fulcrumed on a pivot on the body of the clarinet and having an arm extending forward of said pivot, and a key proper formed with an arm pivotally mounted on the said pivot independently of the forwardly-extending arm of the fingerpiece, the said key-arm being formed with a lateral lug lying under the forwardly-extending arm of said finger-piece, a spring engaging said finger-piece with a tendency to throw the forwardly-extending arm thereof down upon said lug wherebyto close the key proper, and a second spring, weaker than the firstnamed spring and engaging said key proper whereby to throw it open when the forward lyextending arm of the finger-piece is raised from the lug, as and for the purpose set forth.

3. A clarinet provided with a G-sharp key consisting of a finger-piece fulcrumed on a pivot and having an arm extendin forward of its pivot, a key proper pivoted on the same pivot to move independently of said linger piece and having a lateral lug lying under the forwardly-extendingarm of said finger-piece, a spring engaging said finger-piece, with a tendency to throw the forwardly-extending arm thereof down upon the said lug whereby to close the key proper, a second spring weaker than the first-named spring and engaging said key proper whereby to throw it open when the forwardly-extending arm of the finger-piece is raised, and a trilling-lever having one end lying over the key proper, but normally out of contact with the same, the other end of said trilling lever being operatively connected with the key F-sharp, as and for the purpose set forth.

4:. A clarinet provided with a G-sharp key consisting of a pivoted finger-piece having an arm extending forward of its pivot, a key proper pivoted to move independently of said finger-piece and having a lug lying under the f0rwardly-extending arm of said linger-piece, a spring engaging said linger-piece with a tendency to throw the forwardly-extending arm thereof down upon the lug to close the key proper, a second spring weaker than the first-named spring and engaging said key proper with a tendency to throw it open, a trilling-lever having one end lying over the key proper, the said lever being actuated from the key F-sharp, and an arm extending from the finger-piece in the rear of its pivot to a point under the finger-pieces of the keys llnatural and C-sharp, and adapted to be en gaged by either of said finger-pieces, whereby the key G-sharp may be trilled when either of the said l3-natural or C-sharp ii tiger-pieces are depressed,as and for the purpose set forth.
